Home Forums Tax 12b W (HSA contribution) 12b W (HSA contribution) Name * Password * Email chatGPT 가 맞다고 하네요.,, 진짜 맞는건지... Yes — in most cases, that is correct. On your W-2, Box 12 code W (often shown as 12b “W”) represents: Employer and employee contributions to a Health Savings Account (HSA). This amount is informational and is usually not entered directly as income in your tax return. Why it may be omitted When you upload your W-2: The tax software reads Box 12 code W. It uses that number only to calculate your HSA limits and Form 8889. It does not include it in wages (Box 1), Social Security wages (Box 3), or Medicare wages (Box 5). So it may not appear in the income summary section. That’s normal. I agree to the terms of service Comment
